Not really. Even though the story had changed over time and varies from religion to religion and denomination to denomination, God still tends to have a judicial role while Satan tends to have a prosecutorial role.

Dude, I LOVE Christian mythology. It's hard to read up on casually but the Catholics have 100s of saints and the Angel's are pretty well defined.

As for the question? Sure, in an explain like I'm 5 way, good and evil are two different sides to the same coin. But I dont actually think that God and Satan operate in clear lineation like that. And that opinion comes down to something similar to Dissapears, God could wipe out all resistance, but doesnt eliminate Satan, meaning he tolerates it. Good would never tolerate evil. God is either disconnected from their creation or a lie.
